Question and Answer

Is it necessary for a transmitting antenna to be at the same height asthat of the receiving antanna for line of sight communication? A TV transmitting antenna is 81 m tall. How much service area can it cover, if the receiving antena is at the ground level?


Answer: B、C
In LOS communication, it is not necessary that transmitting antenna and receiving antenna are at same height. Only requirement is that there must not be any obsacle in between.
Given, \({h}={81}{m}\)
\(\therefore\) Distance upto which transmission can be made
and, area covered in broadcast
